Area of rectangles and parallelograms and triangles

Front

What is the formula for finding the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for finding the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

What is the formula for finding the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (1/2) × base × height.

Front

If a rectangle has a length of 5 cm and a width of 4 cm, what is its area?

Back

Area = 5 cm × 4 cm = 20 cm².

Front

If a parallelogram has a base of 6 m and a height of 3 m, what is its area?

Back

Area = 6 m × 3 m = 18 m².

Front

If a triangle has a base of 10 m and a height of 5 m, what is its area?

Back

Area = (1/2) × 10 m × 5 m = 25 m².

Front

What is the area of a square with a side length of 7 cm?

Back

Area = side² = 7 cm × 7 cm = 49 cm².

Front

What is the area of a rectangle with a length of 8 cm and a width of 3 cm?

Back

Area = 8 cm × 3 cm = 24 cm².

Front

What is the area of a triangle with a base of 12 cm and a height of 4 cm?

Back

Area = (1/2) × 12 cm × 4 cm = 24 cm².
